Monitoring of volcanic activity: Seismic, Gravimetric, Geomagnetic and Hydrographic monitoring. Deception Island

In English:

The present seismic campaign has carried out the built of a digital
short period seismic network along the inside coast of Deception
Island (Port Foster) and a wide band station. The main aim is to make
a fast location and an energetic quantification of volcanic-tectonic
events, long period volcanic events and volcanic tremors that could
occur during the first week of December 1999. This objective is
focused to notice and check if the seismic episode happened during
January and Februar 1999 was present or not.

Instrumentation:

- Short period seismic station with MARK L4C-3D sensors
- Seismic station with digital vertical component telemetry MARK L4C sensor
- Broad band station, GURALP CMG40T sensor.
- Proton magnetometers, G-856
- Marine magnetometer
- Lacoste-Romberg Gravimeter
- Marine GravimeterTrimble GPS

En Espanol:

La presente campana s?smica ha consistido en el despliegue de
una red s?smica digital de corto periodo a lo largo de la costa
interior de la Isla Decepcion (Puerto Foster) y de una
estacion de banda ancha, con el objetivo principal de realizar una
rapida localizacion y cuantificacion energyetica de
eventos de tipo volcanotectonico, eventos volcanicos de largo
periodo y los tremores volcanicos que pudieran ocurrir durante la
primera semana del mes de Diciembre de 1999. Este objetivo esta
enfocado a observar y comprobar si la crisis sismica ocurrida
durante los meses de Enero y Febrero de 1999 estaba presente o no.
